HELP! Wrote ECU Eeprom BIN to 95040 chip, car runs for 60 seconds, dies,
« on: April 28, 2015, 09:16:01 AM »
Using a Willem type programmer, I wrote the ECU Eeprom file (attached) to my 8D0907551M ECU eeprom. Mount ECU, the car starts and runs for about a minute to 2 minutes, then engine just dies. Try to restart, just cranks. No CEL light when ignition on. no VDCS communication.
I remove ECU and reinstall and the exact same series of events reoccur....car starts, runs for about 1-2 minutes, then dies....
I thought it may be a bad checksum in the ECU eeprom BIN file, but I was told by a very reliable source that the Eeprom BIN is good as it is and ready for use. So, I think that it's got to be another problem. Any ideas???
The eeprom BIN that I am writing to the ECU 95040 Eeprom is attached. If someone could check it to be sure that its checksums are good, I'd appreciate it.

I think the problem is some who else and not the eeprom.
You can test this file, is a working off file without problems.
When it dont helps, buy another ecu en flash the eeprom, or try with cold spray on the pcb.
